Contour Interval: Definaion, Example, Calculations & Uses Is the school likely to be at risk of contamination from this same leak? For example, if you wanted to do a contour line drawing of a pear, you'd simply draw the outline of the pear, add a stem, and stop there. When the contour interval is not specified in the map, it can be calculated as explained in the following sections. 1 ft = 24,000 ft, and 24,000 ft x (\(\frac{1\;km}{3280\;ft}\)) = 7.32 km. What happens when the lithosphere at point X is heated to 1500 C? A profile may be constructed Terms and conditions apply. The headings indicate the direction the Pacific Plate is moving over the hot spot. The desired unit is feet. These circular patterns indicate hilltops, like in the diagram below (Figure 3.6).

TAs names: _______________ _______________. Mathematically, a contour line is a curve in two dimensions on which the value of a function f (x, y) is a constant. If you were standing in the middle on the intermost contour line hill "c", your elevation would be. Examine unconformities 1 and 2 indicated in Figure 1.9. What is the elevation of the unlabeled index contour crossing Roaring Creek in the northwest corner of the map? At 75 km depth, rocks will be heated to about _______ degrees Celsius. Index contours are bold or thicker lines that appear at every fifth contour line. Essentially a topographic profile is a side image of a topographic map, but the image is only a representation of the area shown on the line on the topographic map (line A-B on Figure 3.6). What is the dc collector resistance? Lets assume, 7000 and 7100 and calculate the interval between it. Therefore, if you print it out in black and white please refer back to the electronic copy to avoid confusion. 16. The elevation at sea level is zero meters. Every sixth contour line has an index contour, which is a bolder or thicker line. How to Determine Elevation From a Topographic Map To show different features of Earth's surface. Sometimes vertical exaggeration is desiredbut, in some cases, you may not want it. Contour lines that are far apart show what type of slope? pressing down on the middle mouse wheel and moving the mouse forward and A contour interval is the vertical distance or difference in elevation between contour lines. What is the latitude on the northern edge of this rectangle? Refer to the topographic map in Figure 7-E3 for an example of contour lines you can use to help you complete this question. If the counter interval is 10 feet, which hill (a,b,c) when viewed from the base is 40 feet tall? the "V" points to the area of higher elevation or upstream. See the example under CONTOUR/SPACING below. Note: elevation is metres above sea level; thus, sea level = ______ m. 2. Thus, ais 520'; bis 540'. BIOMEDICINE: Digestive System | Description o. On large-scale maps with a lot of topographical detail, the contour interval is usually smaller, while on small-scale maps with less detail, the contour interval is larger. 6. The lines point toward the center of the depression. To avoid having your profile distorted so that it accurately conveys what the surface of the Earth really looks like in profile, you will want both the vertical and horizontal scales to match. 1) The contour interval between contour is 40m. USGS topographic maps also show many other kinds of geographic features including roads, railroads, rivers, streams, lakes, boundaries, place or feature names, mountains, and much more. Contour lines Contour lines How are the tops of hills, mountains or depressions (dips) shown on a topographic map? Earthwork estimations for any type of structure like bridges, dams or roads can be found out with the help of contour intervals in a map. A thumbnail version of the map is shown in Figure 7-E10, a larger copy is provided at the back of this lab manual, and your TA will provide you with a full-scale version of the map in lab. When she treated such a mixture with EDTA, everything dissociated to 30S30 \mathrm{~S}30S and 50s50 \mathrm{~s}50s particles. . Slope Worksheet- Use the information from the example above and complete the slope worksheet. Why are colors and symbols used on topographic maps? (2 pts) How would the gradient change if you measured from the peak of Guard Mountain (on the east side of the lake, across from Mount Price) to Garibaldi Lake? A person standing at point "F" would only be visible to a person standing at: Examine the figure below. This page titled 3.6: Drawing Contour Lines and Topographic Profiles is shared under a CC BY-SA license and was authored, remixed, and/or curated by Deline, Harris & Tefend (GALILEO Open Learning Materials) . The given point, 537', therefore, must lie between the 520' and 540' contours (contours aand b). To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: (\(\frac{\frac{1000\;ft}{1\;inch})}{(\frac{100\;ft}{inch}}) = 10\).

In above Figure, what is the contour interval of the map? You want to have the y-axis of the graph paper represent the elevations of the contour lines that intersect your drawn line (line A-B in this case). The contour interval is 20'. What is the relief between the surface of East Musquash Lake and the intersection between U.S. Route 1 and Maine Route 6 in Topsfield? Put simply, contour lines mark points of equal elevation on a map. Location A is higher. How far have the snake fossils moved apart since they were originally deposited? What is the contour interval on a map based on? Figure 3. Each contour line shows a different elevation. As contour intervals are for the calculation of vertical elevation of an area, same way to calculate the horizontal distance it is termed as Horizontal Equivalent.
